Fixtures hierarchy convention
-----------------------------
Organizing Fixture Classes and Data Files
-----------------------------------------
Usually you will have one fixture class per needed fixture and will be only switching data files for fixture classes.
When you have simple project that does not have much database testing and fixtures, you can put all fixtures data files under `data` folder, as it is done by default.
But when your project is not very simple you should not be greedy when using data files and organize them according these rule:
By default, fixture classes look for the corresponding data files under the `data` folder which is a sub-folder
of the folder containing the fixture class files. You can follow this convention when working with simple projects.
For big projects, chances are that you often need to switch different data files for the same fixture class for
different tests. We thus recommend that you organize the data files in a hierarchical way that is similar to
your class namespaces. For example,
- data file should follow same hierarchy that is used for your project classes namespace.
Lets see example:
```
# under folder tests\unit\fixtures
```php
#under folder tests\unit\fixtures
data\
components\
some_fixture_data_file1.php
some_fixture_data_file2.php
fixture_data_file1.php
fixture_data_file2.php
...
some_fixture_data_fileN.php
fixture_data_fileN.php
models\
db\
some_fixture_data_file1.php
some_fixture_data_file2.php
fixture_data_file1.php
fixture_data_file2.php
...
some_fixture_data_fileN.php
forms\
some_fixture_data_file1.php
some_fixture_data_file2.php
...
some_fixture_data_fileN.php
#and so on
fixture_data_fileN.php
# and so on
```
In this way you will avoid fixture data collision between tests and use them as you need.

It can be table name, or mongodb collection name if you are using mongodb fixture. In order to know how to specify and name data files for your fixtures read above on this article.
The similar hierarchy can be used to organize fixture class files. Instead of using `data` as the root directory, you may
want to use `fixtures` as the root directory to avoid conflict with the data files.
Same rule can be applied to organize fixtures classes in your project, so similar hierarchy will be build under `fixtures` directory, avoiding usage of `data` directory, that is reserved for data files.
